“The expository mode is the most prominent of all the modes” (Nichols).

This specific mode of documentary forms an argument using rhetorical devices. The main focus of these films is to show images of reality which are used as evidence and logical commentary which is the argument in order to successfully prove their point. Most of these films are going to use sound devices such as Voice-of-God commentary or  Voice-of-Authority commentary in order to strengthen their argument. The filmmakers of these types of films are generally un-biased on the subject of their film in order to be more objective and logical.

Stranger with a Camera is a documentary by filmmaker Elizabeth Barret whom grew up in a middle-class town in Kentucky. Her film focuses on two individuals: Canadian filmmaker Hugh O’Conner and Appalachian resident Hobart Ison and the events that took place following their encounter. She looks at how cultural misunderstandings between these two men ultimately led to the unfortunate death of Hugh O’ Conner. Stranger with a Camera explores the relationship between those who make films for social change and the people whose lives are represented. Barret brings a unique perspective to this film, since she was raised in this community, she is not only the filmmaker but also a subject in her own film. This documentary is a prime example of the expository mode. It poses a rhetorical argument on a social problem that has lasted and been debated in her community for decades. Barret does an excellent job of setting up, and supporting her argument while remaining objective throughout the whole film. She makes good use of interview clips as well as historical film fragments from the town. This film also narrates in a way that directly speaks to the viewer in a logical voice.

The five rhetorical devices used in this mode of documentary are invention, arrangement, style, memory, and delivery. These elements have been used in rhetoric forms of writing for centuries but recently Nichols has tied them into film more specifically the expository form of documentary. Invention is the form of argument that the filmmaker chooses to use, normally being one of the persuasions method (ethos, pathos, and logos). Arrangement organizes the film in the order that most effectively achieves the films rhetorical goal. Style uses arrangement of images and word choice. Memory is important because it allows the speaker to talk  about facts without the need to refer to notes. Finally, the element of delivery allows for visuals to be the message instead of words.
